CHAPTER D.0

D.1Patient table

Description D.1

The patient table has the following functions: D.1

❏ Positioning the patient for the measurement

❏ Securing and positioning the coils used for the meas-

urement

❏ Positioning the patient in the magnet isocenter

The patient table consists of a table and a movable tabletop

securely attached to the table. The supporting frame is directly

installed at the magnet. D.1

The tabletop can be moved horizontally in the magnet bore.

When moved completely out of the magnet, the tabletop may

be moved vertically as well. D.1

(4) Foot end of patient table

The patient table includes 10 coil sockets as well as connec-

tions for the vacuum cushion, headset and squeeze ball. D.1

The patient table is controlled via the control elements. The

relative position and the current movement of the tabletop are

shown on the patient table display (→ Page B.6-5 Patient table

displays). D.1

Patient table positions D.1

To operate the patient table safely and efficiently, operating

personnel has to be familiar with its most important positions. D.1

There are different types of instruction areas: D.1

❏ Lowest position

❏ Innermost position

❏ Outermost and upper position (Home Position)

❏ Last Scan Position

❏ Default Position

❏ Center Position

❏ Relative position

The lowest, innermost, outermost and top positions are end

positions. D.1

Last Scan Position is the relative position of the tabletop for the

last measurement. D.1

When using the default position, the center of the head coil is

located in the magnet isocenter. D.1

When using the center position, the area to be measured is

located in the magnet isocenter. D.1

The relative position of the tabletop measures the distance

between a slice marked with the laser light localizer and the

magnet isocenter. D.1

D.1-90.0

The vacuum cushions are used for comfortable and secure

positioning of various body regions. D.1

The patient can use the headphones to listen to announce-

ments or music during the measurement. They also provide

hearing protection for the patient. D.1

The squeeze bulb allows the patient to get the attention of per-

sonnel during the measurement. An audible signal sounds at

the intercom when the patient squeezes the bulb

(→ Page B.9-1 Description). D.1

D.1-10

Operation D.1

After positioning the patient on the tabletop, the region to be

examined has to be positioned in the magnet isocenter. The

tabletop is moved into the magnet bore. The tabletop cannot be

moved into the magnet bore unless the patient table is at the

correct height (examination height). Similarly, the patient table

can be lowered only if the tabletop is completely moved out of

the magnet bore. D.1

For some measurements, the tabletop is moved automatically. D.1

The buttons Table Movement Up/Inward and Table Move-

ment Down/Outward are used to move the patient table verti-

cally and the tabletop horizontally. D.1

Selecting the Speed button increases the rate of table travel by

one level. D.1

Using the Home Position button, two different positions may be

selected: D.1

❏ Home Position

❏ Last Scan Position

Using the Center Position key, two different positions may be

selected: D.1

Personal injury D.1

Damage to the patient table D.1

✧ Ensure that there are no persons or objects within the haz-

ardous zone of the patient table.

✧ Ensure that the coil, patient or his clothing do not extend

over or hang off the patient table.

✧ Ensure that none of the belts hangs off the patient table.

✧ Ensure that the IV tube does not get caught and that the IV

needle remains in the patient during table movement.

✧ In case of hazardous conditions, press the Table Stop but-

ton.

✧ In case of patients with long hair, ensure that it is not

caught under the moving patient table (have the patient

wear a hairnet, kerchief, paper hat or similar).

✧ Secure the patient’s arms with straps so that the patient is

not caught between the tabletop and the magnet cover.

✧ Stabilize helpless patients using straps.

✧ Explain the significance of protocol-controlled table move-

ments to the patient.
